| Description | This object specifies whether ifIndex values persist across
reinitialization of the device.
ifIndex persistence means that the mapping between the ifDescr
object values and the ifIndex object values will be retained
across reboots.
Applications such as device inventory, billing, and fault
detection depend on the maintenance of the correspondence
between particular ifIndex values and their interfaces. During
reboot or insertion of a new card, the data to correlate the
interfaces to the ifIndex may become invalid in absence of
ifIndex persistence feature.
ifIndex persistence for an interface ensures ifIndex value for
the interface will remain the same after a system reboot.
Hence, this feature allows users to avoid the workarounds
required for consistent interface identification across
reinitialization.
Due to change in syntax, this object is deprecated by
cieIfIndexGlobalPersistence. |
